STATE OFFICE 2 Claims.

This invention relates to improvements in loose leaf binders and has for a principal object the provision of a loose leaf hinder formed of t simple stampings, one of which may be permanently secured to a hinder or cover and the other one of which may be adapted to be placed in cooperative relation with said first stamping.

Another object of the invention is the provision of a loose leaf binder comprised of two stamped members, one of said members being adapted to be associated in pivotal relation to the other and yet readily separable therefrom.

Other objects and advantages will be apparent to those familiar with the art.

Referring to the drawing which illustrates one method of carrying out the invention by way of example:

Figure 1 is a plan view of a loose leaf binder showing the binding members in locked cooperative relation with each other;

Figure 2 is a plan View similar to Figure 1 in which one of the binding members is shown as unlocked from the other and swung through an angle separating the binder rings;

Figure 3 is a plan view of the movable stamped member; 1

Figure 4 is a plan view of the stationar stamped member;

Figure 5 is a cross sectional view taken along the lines 55, Figure 1;

Figure 6 is a cross sectional view taken along the lines 6-4:, Figure 1, showing the locking means;

Figure '7 is a detail, in section, of one end of the stationary stamped members taken along the line 'll, Figure 4; and

Figure 8 is a sketch showing a modification of the form of the ring members.

The stationary member, Figure 4, consists of a fiat longitudinal body it having a plurality of holes it formed therein so that it may be attached to a cover or other suitable folder l2 in any known manner.

A plurality of ears l3 preferably formed integral with the body iii are bent to overlie the body it in spaced relation to the upper face thereof. These ears engage and form guides for the body portion or the movable member, to be presently described, and the space between the ears l3 and the body member is such as will readily accommodate the body of the movable member.

A tab it also preferably formed integral with the body Ill, overlies the upper face of the body It! extending from the same edge thereof as the ears 13, the spaced relation between said tab and.

said face being substantially the same as that between the ears l3 and said face. The tab It also has extending therefrom a segment Ma which forms a locking member, adapted to cooperate with portions of the movable member to be presently described.

A plurality of arcuate elements l5 which in efiect form semi-rings of the binder, are preferably formed integral with the body iii and are provided with V shaped pointed ends I511.

The body it has formed therein near the end thereof a hole It, and a portion Illa of the body is bent to form with the body it a U bend with the hole 96 at the apex of the bend. The space between the body Ii! and the portion Illa forms a channel ll.

The channel I1 is adapted to be engaged by the other member to be presently described and has a boundary stop I8 along the right edge thereof, as viewed in Figure 4.

The movable member, Figure 3, consists of a flat longitudinal body having a tongue l9 extending from one end thereof, said tongue being adapted to extend through the hole It when the end Zila of the body is inserted in the channel H. A plurality of arcuate elements 2| are preferably formed integral with the body 20 and are so spaced that when the body Zil overlies the body Ill the arcuate elements 2! will have their V shaped ends Zia in cooperative relation with the V shaped points 15a of the arcuate elements 25, thereby forming a series of binder rings for retaining the loose leaf sheets 22.

The body has formed therein raised spots 23 and 241 which when the bodies are placed in cooperative relation with each other the raised spot 23 engages the segment [4a, the leading edge Mb of which is curved to permit the raised spot 23 to pass under the segment Ma. with facility.

As the body 28 is swung further to the right the raised spot 24 has its left slanting side in resilient engagement with the right edge of the segment, as may be clearly seen in Figure 6 and thereby the arcuate elements 2| are maintained in cooperative relation with the arcuate elements 115. The lower end of the body 20, as viewed in Figure 3, has one corner bent upwardly and designated by the numeral 25, to be engaged by the thumb or finger to facilitate the associating or disassociating of the members.

As a modification, the arcuate elements which form binder rings may be modified in form to increase the life of the loose leaf sheets 22 in the manner shown in Figure 8 in which the ar- 55 cuate elements l5 may be of curvilinear form, designated at l5b, on a plane at right angles to the arcuate plane and likewise the arcuate element-s 2| may have their portions 2Ib of curvilinear cross section in a like plane.

Although but one species and one modification of this invention have been herein shown and described it will be understood that numerous details may be altered or omitted without departing from the spirit of this invention as defined by the following claims.

What is claimed is:

1. In a loose leaf binder, a cover, a stationary member comprising a fiat longitudinal body having a plurality of ears formed integral therewith partially overlying said body and extending from one edge thereof to form guides, an apertured channel formed at one end of said body, a plurality of arcuate elements formed integral with said body, said elements and said ears being alternately arranged along said body; means for securing said stationary member to said cover; a separable member having a tongue formed on one end thereof adapted to engage the aperture in said channel for associating said separable member with said stationary member in temporary pivotal relation, a plurality of arcuate elements carried by said separable member and adapted to cooperate with said first arcuate elements to form binder rings; and locking means comprised of an L-shaped tab formed integral with said stationary member and overlying one surface thereof and raised spots formed in said separable member adapted to secure the members together when said separable member completely overlies the body of said stationary member and the arcuate elements carried by the separable member are in cooperative relation with the arcuate elements carried by said stationary member.

2. In a loose leaf binder, a cover, a stationary member comprising a fiat longitudinal body carrying a plurality of ears formed integral therewith extending from one edge thereof and having portions overlying the surface of said body to form guides, an apertured channel formed ,in one end of said body, a plurality of arcuate elements formed integral with said body, said ears being interspersed between said arcuate elements; means for securing said stationary member to said cover; a separable member carrying a plurality of arcuate elements adapted to cooperate with said first arcuate elements to form binder rings when said separable member is positioned on said body and engaged by said ears, a tongue formed on one end of said separable member adapted to engage the aperture in said channel for associating said separable member with said stationary member in temporary pivotal relation, and locking means comprised of an L-shaped tab formed integral with said stationary member and overlying the surface thereof and raised portions formed in said separable member adapted to be engaged by said L-shaped tab to secure the members together when said separable member completely overlies the body of said stationary member.
